国际原子能机构新的作用?消除核武器——或是至少削减核武器的数目——仍然是21世纪最严峻的挑战之一。取得进展将需要有效的核查机制,以使任何违背或不履行核军备控制协定的行为及早被探查到,尤其是那些可能危害国际和平与安全的行为。

对于世界各地数百万的伤残人而言,适当的治疗可以改善他们的生活质量。组织移植法是使用经过灭菌的骨、皮肤及其它组织来治愈严重的损伤、创伤和疾病的医疗方法。主要治疗对象包括严重烧伤患者,以及遭受残疾、先天缺陷和失明之苦的男人及妇孺。长期应用于整形外科和矫形外科的组织移植法,曾一度仅使用患者本身的组织进行移植,即进行自体组织移植。但现在人们可以使用人或动物捐献者的组织来进行移植(异源移植)。组织移植法的这种新形式在过去10年已取得巨大发展。现在。

Synthesis of New Polymer Ionomers via Ring-Opening Metathesis Polymerization

Open Journal of Organic Polymer Materials 2014年第4期4卷 84-91页

Topchiev Institute of Petrochemical Synthesis Leninsky Prospect 29 Moscow Russia

The N-pentafluorophenyl-exo-endo-norbornene-5,6-dicarboximide (2a) and N-phenyl-exo-endo-nor-bornene-5,6-dicarboximide (2b) monomers were synthesized and polymerized via ring-opening metathesis polymerization (ROMP) using bis(tricyclohexylphosphine) benzylidene ruthenium(IV) dichloride (I) and tricyclohexylphosphine [1,3-bis(2,4,6-trimethylphenyl)-4,5-dihydroimidazol-2-ylidene][benzylidene] ruthenium dichloride (II). Both catalysts were used to synthesize random and block high molecular weight copolymers which were further hydrogenated using a Wilkinson’s catalyst. Then, the saturated copolymers were modified by reacting with sodium 4-hydroxybenzene-sulfonate dihydrate to generate new ionomers with fluoro-sulfonic acid pendant groups.

AIM： To determine the HLA-DQ locus in Mexican patients with Chronic gastritis and gastric adenocarcinoma.METHODS： Oligotyping for HLA-DQ locus was performed in 45 Mexican patients with chronic gastritis and 13 Mexican patients with diffuse-type gastric adenocarcinoma, and was then compared with 99 clinically healthy unrelated individuals. H pylori infection and CagA status were assessed in patients by enzyme-linked immunosorbent assay （EUSA） method. RESULTS： We found a significant increased frequency of HLA-DQBI＊0401 allele in Hpylori-positive patients with chronic gastritis when compared with healthy subjects [19 vs 0%, P = 1 × 10^-7, odds ratio （OR） = 4.96; 95% confidence interval （95% CI）, 3.87-6.35]. We also found a significant increased frequency of HLA-DQBI＊0501 in patients with diffuse-type gastric carcinoma in comparison with healthy individuals （P = 1 × 10^4, OR = 13.07; 95% CI, 2.82-85.14）.CONCLUSION： HLA-DQ locus may play a different role in the development of H pylori-related chronic gastritis and difffuse-type gastric adenocarcinoma in the Mexican Mestizo population.

Fulminant Hepatitis Associated with Chronic Consumption of 3,4-Methylenedioxy-Methamphetamine;Case Report

引用

Open Journal of Gastroenterology 2024年第5期14卷 161-166页

作者： Ulises Solis Gomez Gustavo Adolfo Hernández Valdez Juan Antonio Contreras Escamilla Ivan Alejandro Medina Jimenez jorge morales Rojas Jocelyn Nataly Quintero Melendez Marco Antonio González Villar Department of Internal Medicine ISSSTE APP General Hospital of Tepic Tepic Nayarit Mexico

The amphetamine derivative 3,4-methylenedioxymethamphetamine (MDMA), also called ecstasy, is a neurotoxin widely consumed among young people that has increased in recent years because it is a recreational drug, of which immediate effects are known such as a greater sensation of well-being, extroversion, increased sensory perception. However, its long-term effects have been described very little in the medical literature, including damage to the heart, central nervous system, kidney, etc. One of its little-known effects is hepatotoxicity, of which few cases are known associated with fulminant hepatitis, which is a rapidly deteriorating condition that is generally associated with a syndrome of multiple organ dysfunction and death. Therefore, it is very important to know this type of damage in the short and long term. The following case is of a 39-year-old man who came to our service due to jaundice syndrome and the only history of MDMA consumption, who as the days went by met the criteria for fulminant liver failure, with damage to multiple organs (organ dysfunction syndrome).
